woon= .wasnine mannin SPECIFICATION forming part of Letters Patent No. 230,152, dated July 20, 1880.

Application filed February 24, 1879. I

Be it known that I, FREDERICK G. SAR- GENT, of Graniteville, in the county of Middlesex and State of Massachusetts, have in-- vented certain Improvements in Wool-Washin g Machines, of which the following is a specification.

My invention relates to that class of machines in which a vat or bowl containing the scouring or cleansing Y liquor is provided with a carrier and fork mechanism for carrying the fiber through the liquor and toward the squeezin g-rolls.

The invention consists in giving the carrier which takes the wool forward and upward over an inclined table to the roll a greater speed" or' number or reciprocal motions in a given time than the fork which delivers the fiber to it, and in providing the inclined table up and over which the fiber passes with toothed ribs having edges in which the teeth are out formed wedge-shaped.

' In the accompanying drawings, in which similar letters of reference indicate like parts, Figure 1 is a longitudinal vertical section of a machine embodying my invention. Fig. 2 is a side view of one of the ribs removed from the machine. Fig. 3 is a cross-section of the same.

A represents the tank or bowl which forms the body of the machine; 13 B, the squeezev rolls; 0, the curved 'orinclined table, extending upward from the bottom of the bowl to the squeeze-rolls.

D is the rake which stirs up the fiber in the liquor in the bowl and carries it forward to the carrier E, which carries it forward and upward on the inclined table to the rolls B B.

The carrier E is actuated by the crank g,. the connecting-rod f, the .roekshaft h, or other suitable mechanism, so that it shall move more rapidly than the swing-rake I), from which it receives the fiber, thus tending to even out the bunches thrown forward by the rake D and present a more even sheet to the rolls B B, which, acting on the fiber-presented.

in a more open and evenly-distributed manner, expels with the liquor more of the dirt and other foreign substances than when they receive it more irregularly. v I

2' is one of the ribs, with a waved or serrated edge upon it. Several of these are placed longitudinally upon the inclined table to prevent the fiber from slipping back into the bowl when deposited upon them.

To obtain the necessary strength for the ribs the metal used in their construction must be of a thickness greater than desirable or necessary for small teeth; and as a large num- 7 her of small teeth, if of proper form, are better than a less number of large teeth, I make the edges of the ribs wedge-shaped and cut the teeth thereon. The manifest advantage of using thesesn all teeth upon the ribs is that when the powerful action of the carrier comes upon the fiber it more readily leaves the teeth without injury and moves forward to the rolls.

What I claim as new and of my invention 1. In combination with rolls B B, bed 0, 7'0

and the rake I the carrier E, constructed so that all its parts shall move in the same direetion at the same time, and arranged to make a greater number of forward movements than the rake I), substantially as described.

'2. In combination with the inclined table (J, ribs reaching below the. surface of the liquid in the tank, having teeth out upon their wedgeshaped edges, substantially as described.

3a In a wool-washing machine, the combi- 8o nation of the rake D, incline-d table (3, rolls, B B, and the carrier E, provided with connected teeth k is, arranged to carry the fiber forward over thetable to the rolls with a greater number of movements than the fork, substan- 8 FREDERICK Gama smeru'r.
